Name ONE thing the plasma membrane does
Physical barrier, selective permeability, communication, cell-cell recognition
What is diffusion?
Material moves from high to low concentratioN
Name ONE function of skin
Protection, Excretion, Maintains body temp, Sensation, Vitamin D production,
Why is the mitochondria the powerhouse of the cell?
It converts nutrients into ATP through cellular respiration
Oxygen is an electron thief which helps produce ATP and release energy for the cell
Name ONE major component of a cell
Cell Membrane, Cytoplasm, Nucleus, Mitochondria, Ribosomes, Rough/Smooth Endoplasmic Reticulum, Golgi Apparatus, Lysosomes, Peroxisomes, Cytoskeleton, Centrosomes, Centrioles, Vacuoles
What is the plasma membrane made of?
Phospholipids
What transport ALWAYS uses carrier proteins?
Active Transport
What hard protein forms the outer skin layer? Give one example
Keratin
Hair, Nail, Skin Glands
Which organelle can be found attached to the ER?
Ribosomes
Why don’t all cells in our body look the same?
Because they have different functions and components!
What fluid does the physical barrier separate?
Extra cellular fluid from the intracellular fluid
Name all 3 passive transport processes that use kinetic energy
Simple diffusion, Facilitated diffusion, Osmosis
Where is the thickest skin?
Palms, Fingertips, Soles of feet
What does the lysosome do?
Break down waste and cellular debris through digestive enzymes
What does a cell have more of if it’s flat?
Cytoplasm organelles
What is the backbone of our triglycerides (in particular, fats)?
Glycerol
What are the two membrane transports?
Active transport and Vesicular transport
What is the 5th layer of the epidermis called?
Stratum lucidum
What is the Golgi apparatus made up of?
What is the Golgi apparatus made up of?
Flattened membranes, modifies sorts, and packed proteins
What part of the plasma membrane helps our immune system?
Cell-Cell Recognition
Which part of the phospholipid is hydrophilic (in contact with water) and faces out
Phosphate head
What is the Na+/K+ pump?
Cytoplasmic Na* binds to the Na*/K* pump, The Na*/K* pump is phosphorylated by ATP, The pump changes its conformation, causing Nat release, K* is released from the pump, The pump returns to its original conformation, Extracellular K* binds to the pump, leading to dephosphorylation
Which of the following is NOT a skin cancer?
Basal cell carcinoma, Dermatocellular carcinoma, Squamous cell carcinoma, Melanoma
Dermatocellular carcinoma
What network of protein filaments and tubules help maintain cell shape and facilitates cell movement and division?
Cytoskeleton
